SWINGING-DOOR HINGE.

Application filed July 13, 1923.

T all whom it may concern:

Be it known that I, J osi ALBnn'ro SosA, a citizen of Mexico, residing at Dawson, in the county of Colfax and State of New Mexico, have invented certain new and useful Improvements in Swinging-Door Hinges, of which the following is a specification.

This invention relates generally to doors, having more particularreference to a door arranged to swing in both directions to open position, the invention having for an object to provide a novel hinge structure for a door of this type which will permit of such swinging and which has combined therewith a braking device to stop oscillation of the door.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. .1 of the drawings is a detail face View of the hinge element of my improved door.

Fig. 2 is a vertical sectional view taken transversely of the hinge element and longitudinally of the door.

Fig. 3 is a plan view of the hinge element, indicating a portion of the door attached thereto.

Fig. 4 is a fragmentary horizontal section taken just below the top of the casing containing the door check.

Fig. 5 is a fragmentary sectional elevational view indicating the normal relation of the catch on the frame to the spring fingers on the door, this view being taken on the line 5-5 of Fig. 4.

In the drawings the reference numeral indicates part of the door, and 11 part of the stile of the door frame. Secured as by screws 12 to this stile is a plate 13 having on one side a casing element 14 which is sunk in a recess in the stile. This plate is formed with a pair of hinge ears such as 15 to which is hinged one side of a leaf 16 whose opposite side is hinged as at 17 to one side of a plate 18 secured as by screws 19 to the edge of the door. WVhen the door swings in one direction from the closed position the leaf 16 swings with the door, and when the door swings in the opposite direction the leaf remains adjacent the plate 13. To ensure of the parts assuming these positions,

as the door swings, a tension spring 20 is connected at one end to a yoke 21 carried by the plate 13 and at its opposite end to a like yoke 22 carried by the plate 18, suitable apertures 23 being formed inthe plates 13 and 18 and the leaf 16 to accommodate this spring, while the yokes 21 and 22 are accommodated respectively in the casing 14 and a recess 24 in the door 10.

To act as a check to the oscillations of the door a pair of spring fingers 28 are fixed to the plate and are adapted to engage behind the offset upper end of a bar 29 slidable vertically in a guide 30 in the casing 14, the fingers 28 curving toward one another at their free ends behind this bar 29. The bottom of this bar rests on one end of a bell crank lever 32 fulcrumed as at 33 in the casing 14 and having its other end adapted to be engaged by the end of a pin 34 fixed to and projecting from the edge of the door. Openings such as 35 are provided in the plate 13 and leaf 16 to receive the fingers 28 and pin 34.

Under normal conditions the tapered top of the bar 29 assumes the relation to the spring fingers shown in Fig. 5, with the fingers able to clear the bar when the door swings open. When, however the door swings rapidly to closed position the pin 34 will strike one end of the lever 32 and raise the other end, which in turn will strike against the bar 29 and lift the latter, which will not have time to descend under the infiuence of gravity before the fingers 28 are bearing against it as the door continues its swing pastclosed position, so that the 'pull of the bar 29 on the fingers 28 checks the movement of the door.

A weak tension spring 40 may be attached to the bar 29 and normally act to urge the latter in a downward direction, and it will be apparent that the degree to which the tapered upper end of the bar is projected into engaging relation with the fingers 28 will depend on the rapidity with which the door is swinging, which determines the force with which the pin 34 strikes the lever 35 so that the braking effect will be greater when the door has been widely opened than when it has been only opened a small degree.

WVhile I have illustrated and described a preferred embodiment of my invention it is to be understood that I do not limit myself to the exact construction herein disclosed, and that various changes and modifications might be made therein without departing from the spirit and scope of the invention as definedv in the appended claims.

Having thus described my invention What I claim as new and desire to protect by Let--- ters Patent of the United States is as fo1- lows: 7 i

In a door, a hinge adapted to permit of the doorswinging freely through the door opening, and acheck for said door comprise ing a pan of oo-operating curved fingers carried bythe door,- and: a slidabl'ebarbarl ried by the door franie 'and adapt-ed to be projected by element on the 'door into the path of said fingerstobe engaged by'the latter as the doorswings awayiro-m' Closed projected by an element on the door into the pathpfsaid fingers, saidxibar having a tapered upper end adapted "to 'be engaged by said fingers as the door swings away from closed position.

3. In a door; a adapted to permit of the door swinging freely through the door opening, and a check for said door comprisng-a pair of..cooperating curved fingers carried by the door and a slidable bar carried by the doorxframewand: adapted to be proj eeted by an element onthe door into "the path oi sai'd ifingersggrandma-z bell teranknleyer adapted to belengagediat *oiie'l end: by sthe said element and at its other endby the said bar to? lift th e." latter into operativeiposition to be engagedv'byijsaid fingers'as-thendmr swings away. from closed'position: i 1" In testimony whereof I have :afiixed my na ure; I 1 4 o JOSE ALBERTO SOSA.
